Got someones I.P and her mum is going crazy, can i get in any trouble for having it?

[Lewis]

Im 14
Her mum is going crazy at me and is threating to "tell the authorities and come into school"
I pranked her into giving me it and ive not done anything with it.
I deleted the messages on facebook but her mum is not convinced and is going to tell me headteacher and if i do anything bad i could get kicked off my £800 rugby tour to Canada

But I do have various Hacking tools on my computer , Booters, RATs , keyloggers Etc.
Can the police get involved and take anything off me and charge me for anything at all?
May sound silly but im kinda worried and just making sure because it was only a joke because everyone thinks im a "Mad Hacker" and im really not wanting in trouble for it :/
What is the most they can do?
Any reply is appreciated
Thanks -Lewis
